In the early days of the Altamira, Fuji's engineers used real-time race feedback gathered from Spanish squad Geox to refine its new frame platform. This two-year R&D process in proved to be a success, eventually leading to the refined Altamira design, as Geox's Juan Jose Cobo relied on his trusty...

It's tough to pull out your bottom bracket with your hands, so we recommend using a specially designed tool if you ever, you know, actually want to get it done. Pedro's Bottom Bracket Wrench 16x39 fits 16-notch, 39mm bottom bracket cups, which basically means that it works with Shimano's XTR BB93...

Extensively tested by the Belkin professional cycling team over the last two years, the Pioneer Shimano Dura-Ace 9000 Power Meter Crankset provides real-time performance data under the most rigorous conditions. It's compatible with ANT+ cycling computers, working best with Pioneer's SGX-CA900 and...

For 2015, Shimano's 105 groupset got a few high-profile upgrades. It's gone to 11-speed, and now has many of the same crankset technologies seen in Dura-Ace and Ultegra. As you'd expect, changes to the cassette and crankset also necessitate changes to the chain that connects them. Shimano...

Though the new naming convention eschews model titles, it's safe to assume that Shimano's CN-HG700 11-Speed Chain is designed with the balance of function and price found in the Ultegra drivetrain -- even though it's actually compatible with any of Shimano's 11-speed drivetrains. As with the...

When you're rockin' down the trail, the last thing you need is a sub-par chain powering your bike. The Shimano CN-HG900 11-Speed chain is the best of the best in the Shimano line of chains and matches with XTR and Dura-Ace like two wingmen in an iconic 1980s pilot flick. This chain was designed...

The 86mm bottom bracket is a relatively new, reasonably beefier BB standard that allows frame designers a little more leeway to play around with seat tube, downtube, and chainstay designs. The new, larger shell requires a larger bracket, obviously, and Shimano designed the Dura-Ace BB86 Bottom...

Rather than use the "wider is better" design that seems to be all the rage, Shimano put the Dura-Ace 9000 C24 Carbon Road Wheelset to wind tunnel testing. The result: the 21mm front and 23mm rear rim depths, coupled with a rim width of a narrow 20. 8mm were found to not only create a smoother...

If you've upgraded your pedals to the Dura-Ace 9000 series, no doubt you're putting in the miles. When your cleats wear out, as they will, you'll need the Dura-Ace 9000 Cleats to keep you locked in. These are the 9000-series Blue cleats, which give you one degree of float, a new option for...

When Shimano's Dura-Ace 9000 came onto the scene, we expected a few bits and pieces to be revamped. Not so with Shimano. Its engineers took an eraser to the drawing board and redesigned the complete component package. Every part is lighter and stronger, with an emphasis on aesthetics. Not to be...
